Description

Door Lock Mortis {DOOR LOCK MORTISE}

Embodiments of the present invention relate to a door lock motive, and more particularly, to a door lock mortise including a latch bolt driving unit capable of operating a latch bolt even when a lever is operated indoors or outdoors.

Typically, a door lock includes a mortise installed inside the door to perform a locking function to control indoor/outdoor access, and a lever installed inside and outside the door for mortice operation to operate the mortis operation.

The above motives include a latch bolt operated by an indoor/outdoor lever, a dead bolt to keep the door locked, and an electric or manual driving means for the operation of the dead bolt. After unlocking the lock by moving the dead bolt using a fingerprint, etc., the door can be opened by operating the outdoor lever to release the latch bolt.

However, the conventional mortis mainly operates the latch bolt by using the friction force between the components, and there is a problem in that the durability of the mortis is deteriorated and the function cannot be performed because the internal components are worn during the operation of the latch bolt.

In addition, since the dead bolt and the latch bolt are released simultaneously with the rotation of the lever, the latch bolt is first released in a state in which the dead bolt is not completely released, so that the door is not opened by the dead bolt.
